Study Notes
Megaloblastic Anemia
- Impaired DNA synthesis leading to abnormal nuclear maturation is associated with Megaloblastic Anemia.
- Macrocytic anemias are characterized by a mean corpuscular volume (MCV) greater than 100 fl.
- Red blood cells (RBCs) in macrocytic anemias are larger than normal.
Vitamin Deficiencies
- Folate deficiency is associated with preventing methylation of dUMP.
- Vitamin B12 deficiency leads to the prevention of thymidine production.
- Vitamin B12 deficiency prevents the production of THF from 5-methyl THF.
Cholesterol-to-Phospholipid Ratio
- Abetalipoproteinemia is associated with disruption of the cholesterol-to-phospholipid ratio.
Effects of Defective DNA Synthesis
- Defective DNA synthesis in megaloblastic anemia leads to abnormal nuclear maturation.
Conditions Not Associated with Megaloblastic Anemia
- Iron deficiency is not associated with megaloblastic anemia.
